Flickr Mashups by David Wilkinson
  =================================
  
  This archive contains all of the code found in my Flickr Mashups book. Many of
  the chapters in Flickr Mashups guide you through a series of steps to build up a
  large and complex source file, often building on material produced by earlier
  chapters. You'll find code files here that correspond to each of the steps shown
  in the book, so no matter where you are in the book, you should be able to find
  a working version of the code you are looking at.
  
  Having multiple versions of code files does make the directory structure a
  little more complicated, so I'd better explain just how it works.
  
  You'll see that there is one folder for each chapter that contains code - in
  other words, pretty much all of them. Where the code within the chapter is
  broken down into a series of steps, you will see a number of sub-folders called
  Step 1, Step 2, Step 3, and so on. The steps correspond roughly to the different
  Try It Out sections of the book, although some of the longer Try It Outs may be
  broken down into two or more steps. Within each Step folder, only the files that
  are modified in that step are included. Where there are multiple steps, you will
  also find a folder named Complete, which contains a complete set of all the
  files required by that chapter. There are also folders that correspond to each
  of the exercises at the end of the chapter.
  
  There is also a Complete folder at the top level of this archive. This folder
  contains the complete set of files for all of the web-based projects in this
  book. This set of files represents the way your mashups web site should look if
  you complete all of the projects and exercises in the book.
  
  Note that none of the third-party libraries are included in this archive. You
  will still need to download and install them as described in the book.
  
  Flickr, together with the other tools and websites used in the projects in the
  book are all live, real-world systems and applications and so they are
  continually changing. If you want to keep abreast of any changes or interesting
  new features and, in particular, details of how this changes might affect
  anything you have read in Flickr Mashups, check my web site at
  http://www.dopiaza.org/. I'll be posting details of anything I find of interest,
  together with a variety of interesting new Flickr remixes and mashups. And of
  course, in the event of there being any errors in the source code included here,
  I'll be sure to post any necessary fixes and updates.
  
  Happy Mashing!
